Challenge 2011 Training Set A

This is a collection of 1000 twelve-lead ECGs, each 10 seconds long, to be used
as a training set for the PhysioNet/Computers
in Cardiology Challenge 2011. The challenge entails determining which of
the similar records in the test sets are acceptable for
interpretation, and which are not.

Reference classifications: The final reference set of classifications
for this training set is now available; records listed
in RECORDS-acceptable are considered on the
basis of currently available information to be acceptable for interpretation,
and those listed in RECORDS-unacceptable are
not.

File formats: The records are provided in both CSV format (.txt
files) and standard PhysioBank format (.hea and .dat files).
The .hea files are short text files that specify the format of the
binary .dat signal files. The formats are those used elsewhere on
PhysioNet; see the FAQ for details. Note that
the last line of each .hea file indicates the age and gender of the
subject if known (unknown ages are recorded as 0, and ages over 89 are recorded
as 90). No other information is available about the subjects of these
recordings.

Download individual files from the list below, or download the entire
dataset as a tarball (set-a.tar.gz,
about 103 MB). See the FAQ if you are
not familiar with unpacking tarballs.
